Diagnosis, monitoring and treatment of systemic lupus erythematosus: a systematic review of clinical practice guidelines.

Objectives: Management of SLE is complex and variability in practices exists. Guidelines have been developed to help improve the management of SLE patients but there has been no formal evaluation of these guidelines. This study aims to compare the scope, quality and consistency of clinical practice guidelines on the diagnosis, monitoring and treatment of patients with systemic lupus erythematosus (SLE). Methods: Electronic databases were searched up to April 2014. The Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument and textual synthesis was used to appraise and compare recommendations. Results: Nine clinical practice guidelines and five consensus statements were identified, which covered seven topics: diagnosis, monitoring, treatment, neuropsychiatric SLE, lupus nephritis, anti-phospholipid syndrome and other manifestations of lupus. The methodological quality of the guidelines was variable, with the overall mean AGREE II scores ranging from 31% to 75% out of a maximum 100%. Scores were consistently low for applicability, with only one guideline scoring above 50%. There was substantial variability in the treatments recommended for class II and V lupus nephritis, the recommended duration of maintenance therapy for class III/IV lupus nephritis (from 1 to 4 years), and timing of ophthalmological examination for patients on corticosteroids. Conclusion: Published guidelines on SLE cover a complex area of clinical care but the methodological quality, scope and recommendations varied substantially. Collaborative and multidisciplinary efforts to develop comprehensive, high-quality evidence-based guidelines are needed to promote best treatment and health outcomes for patients with SLE.DT is funded by a postgraduate scholarship from the Sydney Medical School, The University of Sydney

Patients' Attitudes and Experiences of Disease-Modifying Antirheumatic Drugs in Rheumatoid Arthritis and Spondyloarthritis: A Qualitative Synthesis

Objective.Nonadherence to disease-modifying antirheumatic drugs (DMARDS) in rheumatoid arthritis (RA) and spondy-loarthritis (SpA) results in increased disease activity and symptoms and poorer quality of life. We aimed to describepatients’ attitudes and experiences of DMARDs in RA and SpA to inform strategies to improve medication adherence.Methods.Databases (MEDLINE, Embase, PsycINFO, and CINAHL) were searched to January 2016. Thematic synthesiswas used to analyze the findings.Results.From 56 studies involving 1,383 adult patients (RA [n=1,149], SpA [n=191], not specified [n=43]), we identified 6themes (with subthemes): intensifying disease identity (severity of sudden pharmacotherapy, signifying deteriorating health,daunting lifelong therapy), distressing uncertainties and consequences (poisoning the body, doubting efficacy, conflictingand confusing advice, prognostic uncertainty with changingtreatment regimens), powerful social influences (swayed byothers’ experiences, partnering with physicians, maintaining roles, confidence in comprehensive and ongoing care, valuingpeer support), privilege and right of access to biologic agents (expensive medications must be better, right to receive a biologicagent, fearing dispossession), maintaining control (complete ownership of decision, taking extreme risks, minimizing life-style intrusion), and negotiating treatment expectations (miraculous recovery, mediocre benefit, reaching the end of the line).Conclusion.Patients perceive DMARDs as strong medications with alarming side effects that intensify their disease iden-tity. Trust and confidence in medical care, positive experiences with DMARDS among other patients, and an expectationthat medications will help maintain participation in life can motivate patients to use DMARDs. Creating a supportive envi-ronment for patients to voice their concerns may improve treatment satisfaction, adherence, and health outcomes

“Lupus means sacrifices” – the perspectives of adolescents and young adults with systemic lupus erythematosus.

Background: Disease activity, organ damage and treatment burden are often substantial in children and adolescents with systemic lupus erythematous (SLE), and the complex interplay among the developing child, their parents, and their peers makes effective management difficult. We aimed to describe the experiences and perspectives of adolescents and young adults diagnosed with juvenile-onset SLE to inform strategies for improving treatment and health outcomes. Methods: Focus groups and face-to-face semi-structured interviews were conducted with 26 patients aged 14 to 26 years, from five Australian hospitals in 2013-2014. Focus groups and interview transcripts were thematically analyzed. Results: Five themes were identified: marring identity (misrepresented self, heightened self-consciousness, sense of isolation); restricting major life decisions (narrowed career options, threat to parenthood); multifaceted confusion and uncertainty (frustration of delayed or misdiagnosis, needing age and culturally appropriate information, ambiguity about cause of symptoms, prognostic uncertainty, confronting transition to adult care); resentment of long-term treatment (restricting ambition, animosity towards medication use); gaining resilience (desire for independence, developing self-reliance, recalibrating perceived disease severity, depending on family, trusting physicians). Conclusions: Young patients with SLE perceive they have substantially limited physical and social capacities and restricted personal and career goals. Psychosocial and educational interventions targeted at improving confidence, self-efficacy, disease-related knowledge, social support, and resolving insecurities regarding patients’ capacity for self-management may alleviate psychosocial distress, improve adherence, and thus optimize health outcomes of adolescents and young adults with SLE.DJT is funded by a postgraduate scholarship from the Sydney Medical School, The University of Sydney.

Patients' attitudes and experiences of transition from paediatric to adult healthcare in rheumatology: a qualitative systematic review

Objectives. We aimed to describe patients' attitudes and experiences of transition from paediatric to adult healthcare in rheumatology to inform patient-centred transitional care programmes. Methods. We searched MEDLINE, EMBASE, PsycINFO and CINAHL to August 2019 and used thematic synthesis to analyse the findings. Results. From 26 studies involving 451 people with juvenile-onset rheumatic conditions we identified six themes: a sense of belonging (comfort in familiarity, connectedness in shared experiences, reassurance in being with others of a similar age, desire for normality and acceptance); preparedness for sudden changes (confidence through guided introductions to the adult environment, rapport from continuity of care, security in a reliable point of contact, minimizing lifestyle disruptions); abandonment and fear of the unknown (abrupt and forced independence, ill-equipped to hand over medical information, shocked by meeting adults with visible damage and disability, vulnerability in the loss of privacy); anonymous and dismissed in adult care (deprived of human focus, sterile and uninviting environment, disregard of debilitating pain and fatigue); quest for autonomy (controlled and patronized in the paediatric environment, liberated from the authority of others, freedom to communicate openly); and tensions in parental involvement (overshadowed by parental presence, guilt of excluding parents, reluctant withdrawal of parental support). Conclusion. Young people feel dismissed, abandoned, ill-prepared and out of control during transition. However, successful transition can be supported by preparing for changes, creating a sense of belonging and negotiating parental involvement and autonomy. Incorporating patient-identified priorities into transitional services may improve satisfaction and outcomes in young people with juvenile-onset rheumatic conditions.A.T. is supported by a National Health and Medical Research Council Fellowship (ID 1106716)

Immunosuppressive treatment for proliferative lupus nephritis

Background Cyclophosphamide, in combination with corticosteroids, has been first-line treatment for inducing disease remission for proliferative lupus nephritis, reducing death at five years from over 50% in the 1950s and 1960s to less than 10% in recent years. Several treatment strategies designed to improve remission rates and minimise toxicity have become available. Treatments, including mycophenolate mofetil (MMF) and calcineurin inhibitors, alone and in combination, may have equivalent or improved rates of remission, lower toxicity (less alopecia and ovarian failure) and uncertain effects on death, end-stage kidney disease (ESKD) and infection. This is an update of a Cochrane review first published in 2004 and updated in 2012. Objectives Our objective was to assess the evidence and evaluate the benefits and harms of different immunosuppressive treatments in people with biopsy-proven lupus nephritis. The following questions relating to management of proliferative lupus nephritis were addressed: 1) Are new immunosuppressive agents superior to or as effective as cyclophosphamide plus corticosteroids? 2) Which agents, dosages, routes of administration and duration of therapy should be used? 3) Which toxicities occur with the different treatment regimens? Search methods We searched the Cochrane Kidney and Transplant Specialised Register up to 2 March 2018 with support from the Cochrane Information Specialist using search terms relevant to this review. Studies in the Specialised Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov. Selection criteria Randomised controlled trials (RCTs) and quasi-RCTs comparing any immunosuppressive treatment for biopsy-proven class III, IV, V+III and V+VI lupus nephritis in adult or paediatric patients were included. Data collection and analysis Data were abstracted and the risks of bias were assessed independently by two authors. Dichotomous outcomes were calculated as risk ratio (RR) and measures on continuous scales calculated as mean differences (MD) with 95% confidence intervals (CI). The primary outcomes were death (all causes) and complete disease remission for induction therapy and disease relapse for maintenance therapy. Evidence certainty was determined using GRADE. Main results In this review update, 26 new studies were identified, to include 74 studies involving 5175 participants overall. Twenty-nine studies included children under the age of 18 years with lupus nephritis, however only two studies exclusively examined the treatment of lupus nephritis in patients less than 18 years of age. Induction therapy Sixty-seven studies (4791 participants; median 12 months duration (range 2.5 to 48 months)) reported induction therapy. The effects of all treatment strategies on death (all causes) and ESKD were uncertain (very low certainty evidence) as this outcome occurred very infrequently. Compared with intravenous (IV) cyclophosphamide, MMF may have increased complete disease remission (RR 1.17, 95% CI 0.97 to 1.42; low certainty evidence), although the range of effects includes the possibility of little or no difference. Compared to IV cyclophosphamide, MMF is probably associated with decreased alopecia (RR 0.29, 95% CI 0.19 to 0.46; 170 less (129 less to 194 less) per 1000 people) (moderate certainty evidence), increased diarrhoea (RR 2.42, 95% CI 1.64 to 3.58; 142 more (64 more to 257 more) per 1000 people) (moderate certainty evidence) and may have made little or no difference to major infection (RR 1.02, 95% CI 0.67 to 1.54; 2 less (38 less to 62 more) per 1000 people) (low certainty evidence). It is uncertain ifMMF decreased ovarian failure compared to IV cyclophosphamide because the certainty of the evidence was very low (RR 0.36, 95% CI 0.06 to 2.18; 26 less (39 less to 49 more) per 1000 people). Studies were not generally designed to measure ESKD. MMF combined with tacrolimus may have increased complete disease remission (RR 2.38, 95% CI 1.07 to 5.30; 336 more (17 to 1048 more) per 1000 people (low certainty evidence) compared with IV cyclophosphamide, however the effects on alopecia, diarrhoea, ovarian failure, and major infection remain uncertain. Compared to standard of care, the effects of biologics on most outcomes were uncertain because of low to very low certainty of evidence. Maintenance therapy Nine studies (767 participants; median 30 months duration (range 6 to 63 months)) reported maintenance therapy. In maintenance therapy, disease relapse is probably increased with azathioprine compared with MMF (RR 1.75, 95% CI 1.20 to 2.55; 114 more (30 to 236 more) per 1000 people (moderate certainty evidence).Multiple other interventions were compared as maintenance therapy, but patient-outcome data were sparse leading to imprecise estimates. Authors’ conclusions In this review update, studies assessing treatment for proliferative lupus nephritis were not designed to assess death (all causes) or ESKD. MMF may lead to increased complete disease remission compared with IV cyclophosphamide, with an acceptable adverse event profile, although evidence certainty was low and included the possibility of no difference. Calcineurin combined with lower dose MMF may improve induction of disease remission compared with IV cyclophosphamide, but the comparative safety profile of these therapies is uncertain. Azathioprine may increase disease relapse as maintenance therapy compared with MMF.Internal support - Cochrane Kidney and Transplant, Australia.

Executive summary of the 2020 KDIGO Diabetes Management in CKD Guideline:evidence-based advances in monitoring and treatment

THE KIDNEY DISEASE: Improving Global Outcomes (KDIGO) Clinical Practice Guideline for Diabetes Management in Chronic Kidney Disease represents the first KDIGO guideline on this subject. The guideline comes at a time when advances in diabetes technology and therapeutics offer new options to manage the large population of patients with diabetes and chronic kidney disease (CKD) at high risk of poor health outcomes. An enlarging base of high-quality evidence from randomized clinical trials is available to evaluate important new treatments offering organ protection, such as sodium-glucose cotransporter-2 inhibitors and glucagon-like peptide-1 receptor agonists. The goal of the new guideline is to provide evidence-based recommendations to optimize the clinical care of people with diabetes and CKD by integrating new options with existing management strategies. In addition, the guideline contains practice points to facilitate implementation when insufficient data are available to make well-justified recommendations or when additional guidance may be useful for clinical application. The guideline covers comprehensive care of patients with diabetes and CKD, glycemic monitoring and targets, lifestyle interventions, antihyperglycemic therapies, and self-management and health systems approaches to management of patients with diabetes and CKD

Structural change in a B-DNA helix with hydrostatic pressure

Study of the effects of pressure on macromolecular structure improves our understanding of the forces governing structure, provides details on the relevance of cavities and packing in structure, increases our understanding of hydration and provides a basis to understand the biology of high-pressure organisms. A study of DNA, in particular, helps us to understand how pressure can affect gene activity. Here we present the first high-resolution experimental study of B-DNA structure at high pressure, using NMR data acquired at pressures up to 200 MPa (2 kbar). The structure of DNA compresses very little, but is distorted so as to widen the minor groove, and to compress hydrogen bonds, with AT pairs compressing more than GC pairs. The minor groove changes are suggested to lead to a compression of the hydration water in the minor groove

Executive summary of the KDIGO 2022 Clinical Practice Guideline for Diabetes Management in Chronic Kidney Disease:an update based on rapidly emerging new evidence

The Kidney Disease: Improving Global Outcomes (KDIGO) 2022 Clinical Practice Guideline for Diabetes Management in Chronic Kidney Disease (CKD) represents a focused update of the KDIGO 2020 guideline on the topic. The guideline targets a broad audience of clinicians treating people with diabetes and CKD. Topic areas for which recommendations are updated based on new evidence include Chapter 1: Comprehensive care in patients with diabetes and CKD and Chapter 4: Glucose-lowering therapies in patients with type 2 diabetes (T2D) and CKD. The content of previous chapters on Glycemic monitoring and targets in patients with diabetes and CKD (Chapter 2), Lifestyle interventions in patients with diabetes and CKD (Chapter 3), and Approaches to management of patients with diabetes and CKD (Chapter 5) has been deemed current and was not changed. This guideline update was developed according to an explicit process of evidence review and appraisal. Treatment approaches and guideline recommendations are based on systematic reviews of relevant studies and appraisal of the quality of the evidence, and the strength of recommendations followed the “Grading of Recommendations Assessment, Development and Evaluation” (GRADE) approach. Limitations of the evidence are discussed, and areas for which additional research is needed are presented
